nir: const_index helpers
Direct access to intr->const_index[n], where different slots have
different meanings, is somewhat confusing.
Instead, let's put some extra info in nir_intrinsic_infos[] about which
slots map to what, and add some get/set helpers. The helpers validate
that the field being accessed (base/writemask/etc) is applicable for the
intrinsic opc, for some extra safety. And nir_print can use this to
dump out decoded const_index fields.
